The uneven distribution of ground-based instrumentation in some regions makes it a
challenge to study, understand and model ionospheric dynamics. This is so particularly in
the African sector where less has been done about space weather studies. This project is
looking at modelling total electron content (TEC) derived from global navigational satellite
systems with the aid of relevant geophysical inputs. Modelling techniques under
consideration include empirical orthogonal functions, regression analysis and neural
networks. It is intended that the outcome will be an empirical model capable of predicting
TEC on a regional scale during geomagnetic disturbed conditions.

The Space Science Directorate of SANSA is host to the only Space Weather Centre in Africa providing early warnings and forecasts on space weather activity, playing an important role in protecting satellite technology, communication and navigation systems.
